repo-memory-graph

repo-memory-graph is a skill for Claude Code, Codex from DVNghiem/FlowDeck. It costs 31 tokens per session (453 once invoked), scanned A, original, MIT.

A persistent knowledge graph for one codebase, recording its modules, dependencies, coding conventions, bug history, and ownership. A knowledge graph stores connected facts so they can be retrieved later.

In plain words
What is it for?
Use it when mapping a repository, onboarding modules, recording recurring bugs, or tracking how refactoring changes module ownership and relationships.
Why use it?
It keeps important repository knowledge available between tasks instead of making the agent rediscover how the project is structured each time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

repo-memory-graph scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Repo Memory Graph

The Repo Memory Graph is FlowDeck's long-term knowledge store about this specific codebase. It persists in ~/.fd-plan/<slug>/.codebase/MEMORY.json and grows over time.

What Gets Stored

  • Modules: files, their type (service/api/schema/config), owner, tags
  • Dependencies: which modules import or call which others
  • Conventions: patterns used in this repo (naming, error handling, auth flow)
  • Bug history: which modules have had recurring issues
  • Ownership: who owns what (from git blame, CODEOWNERS, or explicit annotation)

When to Update

Update the graph:

  • After /fd-task maps the codebase during init
  • When onboarding a new module
  • When a bug fix reveals a recurring pattern (add to bug_history)
  • When a refactor changes module ownership

Usage with repo-memory tool

// Write a node
{ "action": "write_node", "node_id": "auth-service", "node": {
    "type": "service", "path": "src/services/auth.ts",
    "owner": "security-team", "tags": ["auth", "jwt"],
    "dependencies": ["user-model", "token-store"],
    "dependents": ["api-gateway", "session-handler"],
    "bug_history": ["jwt-expiry-bug-2024-03"],
    "conventions": ["always validate token before processing"]
}}

// Query by owner
{ "action": "query", "query": { "owner": "security-team" } }

How Agents Use This

  • Impact Radar: walks the dependency graph to find affected modules
  • Blast Radius: traverses dependents to map downstream risk
  • Regression Prediction: uses bug_history to weight risk categories
  • Architectural Constraint Guard: checks module boundaries before allowing edits
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

repo-memory-graph is a skill published in the GitHub repository DVNghiem/FlowDeck (24 stars, last pushed 18d ago), licensed MIT. It adds 31 tokens to every session and 453 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
